python struct pack displaying ascii -

उपयोग करते समय 

  आयात संरचना struct.pack ("& gt; H", 31001)   
 आउटपुट  'y \ x19'  है, जब मुझे उम्मीद थी  '\ x79 \ x19'  मुझे पता है कि \ x79 एएससीआईआई में है, लेकिन क्या जानकारी समान है? ऐसा क्यों है कि एक बाइट जब दूसरे नहीं है, तब क्या हुआ? मैं एक modbus कमांड भेजना चाहता हूं और सोच रहा हूं कि क्या यह एक संचार समस्या पैदा कर रहा है। मैं modbus के लिए नया हूँ और मुझे यह पता चलने में परेशानी हो रही है कि दास स्वामी को क्यों नहीं जवाब देगा।   
 
 
 आप  repr ()  फ़ंक्शन के परिणाम को देख रहे हैं, जो पायथन इंटरैक्टिव दुभाषिया सभी परिणामों पर उपयोग करता है जो  None  नहीं हैं।  
 पायथन स्ट्रिंग सामग्री ASCII के लिए प्रिंट करने योग्य,  \ r ,  \ n  और  \ t  के लिए ASCII  टेक्स्ट  का उपयोग करके दिखाया जाता है कैरेज़ रिटर्न, न्यूलाइन और टैब वर्ण क्रमशः, और  \ xhh  हेक्स शेष के लिए बच निकले हैं।  
 और हाँ,  '\ x79'  सटीक समान है बाइट के रूप में  'y' :  
  & gt; & gt; & gt; 'Y' == '\ x79' सच है   
 लेकिन प्रतिनिधित्व करते समय, पायथन बस आपको प्रिंट करने योग्य ASCII वर्ण दिखाता है:  
  & gt; & gt; & gt; '  
 अगर आप  सभी  कोडपॉइंट को दिखाना चाहते हैं तो आप स्ट्रिंग को  'hex'  में एन्कोड कर सकते हैं हेक्साडेसिमल:  
  & gt; & gt; & gt; 'Y \ x19'.encode (' हेक्स ')' 7919 '

java - Why my included JSP file won't get processed correctly? -

-
I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it. First of all, I want the following index.jsp : & lt; Body & gt; Use all pages to be created. & Lt;% @ include file = "header.jsp"% & gt; & Lt; Hours / & gt; & Lt;% @ included file = "body.jsp"%> & Lt; Hours / & gt; & Lt;% @ include file = "footer.jsp"% & gt; & Lt; / Body & gt; And, in body.jsp , I should have it like this: & lt; Jsp: include page = "$ {Application_modul}"%> Where application_modul is an attribute defined in its controller: request.setAttribute ("application_modul", "USER_ACCOUNT \\ ' View_user_account.jsp "); This file can be found properly, but the processed JSP does ...

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
